ON FILE SYSTEMS WITHOUT HARDWARE SNAPSHOT CAPABILITY, P5 creates and
maintains the snapshots using soft and hard links. This includes for

Starting with V3, PresSTORE supports extended file attributes on Linux
and, as a consequence, is able to properly save and restore additional
user rights of the files managed by the Novell Storage Services on
Linux.

When Synchronizing files from Unix / OSX to Windows, owner and group attributes cannot be converted 1:1. Because of that, the files are set to be owned by the local administrator account in the local administrator group on Windows. In the opposite directi...
